OBJECTIVE To analyze the effect of folic acid-fortified foods on the prevalence of neural tube defects in live newborns. METHODS Longitudinal study with newborns from the city of Recife, Northeastern Brazil, between 2000 and 2006. Data analyzed were obtained from the Sistema Nacional de Informações de Nascidos Vivos (National Information System on Live Births). Neural tube defects were define...

climatic parameters in time and space scales of change are for many reasons of changes and how they should be based on observations using a statistical method to be determined. analysis of the most widely used statistical methods that assess potential climate change on hydrological time series, such series of precipitation, temperature and flow rate used. this study of 11 synoptic,rain gage and...

the interaction between sea and atmosphere has profound effects on the regions climate. meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...

Suhu udara permukaan (SUP) merupakan salah satu indikator penting dalam konteks terjadinya perubahan iklim. Penelitian ini bertujuan untuk mengkaji variasi temporal dan spasial beserta trend SUP di Pulau Jawa pada tahun 1990-2019. Data yang digunakan diperoleh dari observasi Badan Meteorologi Klimatologi Geofisika (BMKG) data pemodelan reanalisis (GHCN_CAMS, ERA-5, JRA-55, GISTEMP-v4). BMKG ber...

in this study, long-term trends and abrupt changes of hydro-climatic variables was investigated in the observed period 1971-2000 for aidoghmoush basin using mann-kendall nonparametric test and cumulative curve of climatic variables-runoff, respectively. results show decrease trends for rainfall and runoff and increase trend for temperature by the mann-kendall test with a confidence level of 99%...

The purpose of this paper is to investigate the trend precipitation in Kilkis region (Greece) at site and regional level various time scales. At level, was analyzed using three tests: 1) Mann-Kendall, 2) Sen’s T 3) Spearman while slope estimated estimator. a nonparametric spatial tests such as Regional Average Mann-Kendall (RAMK) BECD’s (Bootstrap Empirical Cumulative Distributions) were elabor...

rainfall and flow rate are of the most important climatic and hydrologic parameters whose investigation and determination of their behavior are of great importance in water resources management. one of the most suitable methods available for assessment of hydro-climatological conditions in the watershed is trend analysis which is used to examine the changes of a variable during time. current st...

Temperature is one of the most important climate variables that many economic and social plans related to its changes. Because of The importance of this issue, this study investigated the changes of it in the province Khuzestan. Meteorological data that used in this study is mean temperature in annual and seasonal timescale. The study area is Abadan, Ahwaz, Dezful and Omidiye stations. For anal...
